29d53d19f3 Kirkwood: allow to override CONFIG_SYS_TCLK
This patch allow to override CONFIG_SYS_TCLK from board configuration
files. This is needed for the Network Space v2 which use a non standard
core clock frequency (166MHz instead of 200MHz for a 6281 SoC).

As a possible enhancement for 6281 and 6282 devices, TCLK could be
dynamically detected by checking the Sample at Reset register bit 21.

Additionally this patch fix a typo.

24a514c445 da850evm: fix NAND WSTROBE and TA timings
The current NAND timings, introduced in commit
a3f88293dd da850evm: setup the NAND flash
timings , incorrectly set WSTROBE and TA to 0. A more recent inspection of the
values set by the Linux kernel indicates that these should be set to 1.

Set the WSTROBE and TA field of the EMIFA cycle-count timings configuration to
1 to match the values set by linux.

68cebb8027 MIPS: Move timer code to arch/mips/cpu/$(CPU)/
Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available.  But this doesn't always work.

We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources.  And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.

With this change, each $(CPU)/ directory can have its own timer code.

0abddf82d5 cmd_ide: enhance new feature "CONFIG_IDE_AHB"
Although most IDE controller is designed to be connected to PCI bridge,
there are still some IDE controller support AHB interface for SoC design.

The driver implementation of these IDE-AHB controllers differ from other
IDE-PCI controller, some additional registers and commands access is required
during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is
required to be defined to support these kinds of SoC controllers. Such as
Faraday's FTIDE020 series and Global Unichip's UINF-0301.

e89516f031 zlib: split up to match original source tree
While looking to upgrade to zlib-1.2.5, the current mondo merge of
multiple files into a single was making things way more difficult
than it should have been.  Hard to pick out what has been changed
to port it to U-Boot, been removed as useless, and bug fixes added
after the fact.

So split the single file up into the original file names, and merge
non-essential changes back from the original tree (for some reason,
style in code in a bunch of places was changed to U-Boot style even
though this isn't "U-Boot" code).

The original build style is retained -- we have a single zlib.c that
includes all the other files, and that is the only file we compile.

83b7e2a7f2 Handle most LDSCRIPT setting centrally
Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk.  Some
are found using an arch-specific rule for looking in CPUDIR, etc.

Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.

Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.

If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.

If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:

$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds

Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules.  These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

a21b5d4bfd ppc, arm: rework and enhance keymile-common.h

  - introduce "bootrunner" environment variable
    This allows to execute consecutive different commands
    specified in the list "subbootcmd". If one command fails
    the command serie will stop.
  - introduce environment variable "develop", "ramfs" and "release"
    Each variable is one way to boot our linux. "develop" is for
    development purpose and boots the SW via NFS. "release" is for
    booting the linux image from flash, "ramfs" allows to load an SW
    image via tftp into ram and executes from there
  - introduce "addmem" variable, this command adds the used memory
    for linux to the bootargs
  - introduce "addvar" variable, this command adress for the /var
    directory to the kernel command line
  - introduce "setramfspram" and "setrootfsaddr" these calculation
    were done if "ramfs" was used (only for debugging)
  - introduce "tftpramfs" used for "ramfs" to load the image into
    RAM (only for debugging)
Remove unneeded stuff:
   - CONFIG_IO_MUXING is obsolete for keymile boards
   - CONFIG_KM_DEF_ENV_PRIVATE is also obsolete
   - define CONFIG_SYS_TEXT_BASE in board configs only

6c11aeafef keymile, common; fix i2c deblocking support
This patch fix the i2c deblocking facility with the i2c HW-Controller.
The required delays for byte reading, the enhanced criteria for stop
the dummy read and required 5 start/stop sequences are added.

Add i2c deblocking before ivm eeprom read.

Improve i2c deblocking sequence by respecting stop hold time.

Cleaned function for deblocking. Have now one function i2c_make_abort()
available for bitbang, mpc82xx and mpc83xx harware controller.

8ed74341ba ppc, 8321: cleanup tuxa1, tuda1 and suvd3 support
For the kmsupx5 a new header file was introduced km8321-common.h.
Now the common stuff from tuxa1, tuda1 and suvd3 was removed and
the new header file included.

The defines CONFIG_SYS_PIGGY_BASE and CONFIG_SYS_PIGGY_SIZE are
confusing. Because they actually describe the KMBEC FPGA values.
The KMBEC FPGA can be PRIO on kmeter1 or upio on mgcoge. Therefore
all the defines were renamed.

remove unneeded variable CONFIG_KM_DEF_NETDEV, as it is
already declared in keymile-common.h

1ebbb77a19 km_arm: change some register values for SDRAM initialization
These new values are:
- enables UART0 and UART1 pins in MPP
- define some L2 cache settings
- changes a SDRAM timing to better fit the hardware
- removed three writes that were the same as the reset values

44097e26cc km-arm: i2c support for suenx based boards
This patch renames the suen3 defines and functions to KM_KIRKWOOD
which is more generic and more precise, because these values
and functions where used by all suenX boards and not only suen3.

af895e4527 ppc: add support for ppc based board mgcoge2ne
The mgcoge2 board from keymile deploys two different processors.
An ARM based Kirkwood for the "unit" part of the SW and a PPC for
the "ne" part of the SW. Therefore in Linux and U-Boot the names
for the board are mgcoge2un and mgcoge2ne. This patch adds the
mgcoge2ne part of the board. The ppc part of mgboge2 is quite
similar to mgcoge, therefore a generic header km82xx-common.h
was introduced to collect all similiarities. Currently the only
difference is that mgcoge2ne has a 64 MB numonyx NOR flash with
a single die. The mgcoge has a dual die flash 2*32MB from spansion.
